Hello, I am trying to open a file from the Umbraco Media library as a stream so that I can add it to a Zip archive to return to the user. However I'm using the Azure Blob Storage for media storage so it's not on the filesystem itself. I keep getting errors that the file does not exist or other null references. Am I trying to get it via an incorrect way or is this something that is not possible? I am using the

MediaFileManager.FileSystem

to get to the filesystem to use FileExists and OpenFile etc.

I want to preface this with saying I am not an expert on blob storage file streams at all, but Microsoft seems to have some documentation about getting items from blob storage into a stream (which I assume you could then move into your .zip as desired). https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-download#download-to-a-stream

There is also an Umbraco specific approach, that may be a bit easier to work with. You can inject

MediaFileManager

. It has a

FileSystem

property, which again has a

OpenFile

method. Eg.:

using Stream stream = _mediaFileManager.FileSystem.Open("/media/egpmoga4/froe.jpg");

Does that work with Azure storage?

Yup

Sweet, I learned something today 😄

The whole point is that Umbraco provides an abstraction for the file system, so you don't have to worry about whether media fiels are stored on disk, Azure blob storage. I haven't worked with Amazon, but I think that should work the same way.

Thanks, Anders! I've started working with some clients with Azure storage recently but many of our clients are self-hosted (government likes that for some reason), so it's something I'm still digging into.

I am working with the

MediaFileManager

as mentioned in the post but for some reason it doesn't want to open a stream to the file

Yes, the path for the

OpenFile

method shouldn't be a full/absolute path, but the one you get from the

umbracoFile

property or

media.Url()

.

My mistake, thanks to both of you for helping!
